TANK-HEATER.

SPECIFICATION forming part of Letters Patent No. 715,895, dated December 16, 1902.

lImplication :filed .Tuly 24, 1902. :Serial No. 116.871. (No model.)

To @ZZ 1072.011?. if, may concern:

Be it known that I, JOEL STRAHM, a citizen of the United States, residing at Sabe-tha, in the county of Nemaha and State of Kansas, have invented certain new and useful' vInh'- provements in Tank-Heaters, of which the following is a specification.

This invention relates to heaters chieliy designed for preventing water from freezing in cold weather and for raising water to the boiling-point in tanks, barrels, and like'receptacles for cooking feed for stock or any purpose requiring the use of scalding Water.

The invention-purports to be an improvement on the tank-heater patented by` me May 27, 1902, No. 700,854, the parts beingV more compactly arranged and the general structure altered so as to enhance the value of the heater both in its make-up and operation.

For a full description of the invention and the merits thereof and also to acquire aknowledge of the details of construction Vof lthe means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a vertical central section of a heater embodying the invention. Fig. 2 is a perspective view of the base, the {jre-basket a'nd body being removed. Fig. 3 is a perspective view of the body portion of the heater inverted, the clamp-band being movedaway Fig. 4. is a perspective view of the tire-basket. Fig. 5 is a perspective view of the heater, parts being broken away to show more clearly the internal construction and arrangement of the parts. Fig. 6 is a detail view of the upper portion of the body and the outlet-pipe at the side thereof, showing more clearly the slots to admit of the smoke-pipe (not shown) being iitted to` the upper end of the outlet-pipe. Y Corresponding and like parts are 4referred to in the following description and indicated in all the views of the drawings by the same reference'characters.

It is the intention to construct the heater of different sizes, according to the work to be I performed, and the parts, such as the base and body, may be either cast wholly or in part or formed of sheet or plate metal bolted or riveted together.

' The base l is hollow and approximately circular in horizontal section, the top being provided with openings 2 and 3, which are in communication, the opening 2 being comparatively large and arranged slightly to one side of the vertical center of the base and the 'opening 3 being comparatively small to provide an outlet for smoke and products of combustion.y A vertical rim or fiangeencircles the openings 2 and 3 and is adapted to enter the lower end of the body 5 and outlet 6. A groove 7 is formed in the top of the base eX- terior andV adjacent to the rim or iiange 4 and receives the lower end of the parts 5 and 6, together with any good cement to insure the formation of a tight joint between the upper and lower parts of the heater.

The body 5 is of cylindrical form, and its lower end is of a size to snugly fit over and receive the vertical rim or ange 4. and is progroove 7, so as to form a close joint therewith, and also to receive the strain of the clamp-band 9 when tightened to draw the upper and lower parts of the heater together.

The outlet 6 is a pipe or tube provided at one sidecf the body 5, and its lower end has an outer flange forming, in eect, a continuation of the liange S and for a like purpose. The lower end of the outlet 6 snugly ts about the vertical rim or ange 4, surrounding and in line with the outer edge of the opening 3. The lower end of the body adjacent to and separating the outlet from the body is provided with notches lO, corresponding with the parts of the rim or ange at opposite sides of the opening 3, so as to admit of the flange 8 entering the groove 7.

space between the parts 0f the rim or iiange 4. at the juncture of the two openings 2' and 3.

`The clamp-band 9 snugly encompasses the The part of the body` intermediate of the notches l0 enters the vided with lan outer flange S to enter the IOO band and top of the base. The cover or top 12 for closing the upper end of the body 5 is provided with a handle and likewise with a damper 13 for controlling the admission of air.

The fire-basket 14 is provided at its upper end with an outer flange a, and its lower portion has its bottom and sides slotted to form a series of gratebars b, which support the fuel, the spaces between the grate-bars providing an escape for the ashes and entrances for the air for supporting combustion. The grate-bars likewise distribute the air, whereby the fuel is caused to burn uniformly, which is essential for an equalization of the heat when the device is in active service. The lire-basket is suspended from the llange or rim 4, surrounding the opening 2, by its outer flange engaging thereover. Lugs 15 are cast with the dre-basket at diametrically opposite points and receive the ends of the bail 16, by means of which the fire-basketislowered into the heater or removed therefrom.

A smoke-pipe (not shown) may be fitted to the upper end of the outlet 6 to carry olf the smoke and products of combustion to a convenient point of discharge. The heater is adapted t0 be arranged Wit-hin the tank, barrel, cask, or reservoir containing water to be heated or food to be cooked, and it is secured in place, so as to prevent displacement by rotation or otherwise. The fire being started in the fire basket, air is supplied thereto through the damper 13, and the smoke and products of combustion pass out through the outlet 6, the fire being regulated by opening the damper more or less, as will be readily understood. The burned embers, ashes, and the like may be readily removed by withdrawing the fire-basket from the heater through the body 5 after removing the cover or top 12 and after the contents of the fire-basket have been dumped. The said basket is readily replaced through the body and is properly positioned by the flange at its upper end engaging with the rim or flange 4. The removability of the fire-basket, besides providing a convenient means for cleaning the same and removing ashes from the base, also enables the fire-basket to be replenished preliminary to starting the lire, which is of vital consequence in point of convenient and ease of operation.

The fire-basket 14 is removably tted within the base, and its upper unslotted portion forms, with the upper portion of the base, an annular chamber for reception of the products of combustion and smoke, which find au escape through the outlet-pipe 6. Slots 17 separate the upper portion of the outlet-pipe 6 from the body 5 and are adjacent to the latter, so as to admit of the smoke-pipe (not shown) coming close against the body 5 and receiving the upper portion of the outlet-pipe 6, as will be readily comprehended.

Having thus described the invention, what is claimed as new is- 1. In a heater of the character described, a hollow base provided in its top with a large and a small opening in communication, a vertical rim surrounding and in line with said openings, a body provided at one side with an outlet, an outer llange at the lower end of the body and outlet to snugly t over the aforementioned vertical rim, and a clamp-band applied to the body and outlet and adapted to secure it to the said base, substantially as set forth.

2. In a heater of the character described, a hollow base provided in its top with a large and a small opening in communication, a vertical rim surrounding and in line with said openings, a groove in the top of the base eX- terior and adjacent to the vertical rim, the body provided at one side with an outlet, an outer flange at the outer end of the body and outlet to tit over the Vertical rim and enter the groove, and a clamp-band applied to the body and outlet and adapted to be secured to the top of the base,substantially as described.

3. In a heater of the character described, a hollow base provided in its top with a large and a small opening in communication, a vertical rim surrounding and in line with the said openings, and a body provided at one side with an outlet and adapted to have its lower end fitted about the said vertical rim, the lower end of the body adjacent to the outlet being provided with notches to receive the parts of the said vertical rim at opposite sides of the small opening, substantially as specifled.

4. In a heater of the character described, a hollow base provided with a large and a small opening,a vertical rim surrounding and in line with said openings, a body provided at one side with an outlet and having the lower end of the body and outlet fitted to the said vertical rim, and a lire-basket provided with a bail and removable through the said body and provided at its upper end with an outer flange to rest upon the aforesaid vertical rim and hold the dre-basket in suspension Within the base, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
